Renesas Introduces Power Management IC for AI Applications


Renesas Electronics Corporation has introduced the RAA215300 PMIC (Power Management IC) optimized to complement Renesas’ RZ/V2L and RZ/G2L microprocessors (MPUs) designed for AI-enabled applications. The new high-performance PMIC offers a wide range of features, including nine channels, a built-in charger, and a real-time clock. The high integration of the new device reduces design complexity, speeding time-to-market for customers.

The RAA215300 includes six buck regulators, three LDOs, and a coin cell/super cap charger. It supports DDR4, DDR4L, DDR3, and DDR3L memory with dedicated VREF, VTT, and VPP rails. The new PMIC enables four-layer printed-circuit boards, which reduce costs. The high level of integration also increases system reliability due to fewer system components needed on the board.

The RAA215300 pairs with the RZ/G2L, RZ/V2L, and several other Renesas offerings in a Winning Combination for a Scalable SMARC (Smart Mobility Architecture) SoM System-on-Module with AI design. In addition to the Renesas MPU and PMIC, this Winning Combination includes power controllers, a USB PD controller, and a clock device from Renesas. Renesas offers over 250 of these Winning Combinations that consist of complementary analog, power, timing devices, and embedded processing, and provide an easy-to-use architecture. They simplify the design process and significantly reduce design risk for customers in a wide variety of applications.

“Customers of our RZ/V2L and RZ/G2L MPUs will enjoy the performance advantages and ease-of-design of the RAA215300,” said Andrew Cowell, Vice President, Mobility, Infrastructure, and IoT Power Business Division at Renesas. “In addition, its high integration and rich feature set make it an excellent choice for consumer, industrial and SoM applications.”
